Music of the Sun is the debut album by Barbadian recording artist Rihanna, released by Def Jam Recordings on August 12, 2005. Prior to signing with a record label, Rihanna was discovered by record producer Evan Rogers, who helped Rihanna record demo tapes which could be sent out to potential record labels. After Rihanna was signed by Jay-Z, the former Chief executive officer (CEO) and president of Def Jam, she continued to work with Rogers and his production partner Carl Sturken, as well as working with other producers for her debut album. The album features vocals from artists including Kardinal Offishall, J-Status, and Vybz Kartel. Music of the Sun features Caribbean-influenced dance-pop, dancehall music, and R&B ballads.
